At present, high-power household appliances on the market are roughly classified into two categories: resistive and inductive. Resistive load household appliances use pure resistance as the load parameter. When the current passes, it will be converted into light energy and heat energy, such as incandescent lamp, electric kettle, electric wok, rice cooker, electric iron and so on. Inductively loaded household appliances convert electrical energy into mechanical energy or other forms of energy, such as electric motor-powered washing machines, refrigerators, range hoods, electric fans, air conditioners, and the like.

The capacity range of commonly used household appliances is as follows: microwave oven is 600-1500 watts; rice cooker is 500-1700 watts; induction cooker is 300 watt-1800 watts; electric wok is 800-2000 watts; electric water heater is 800-2000 watts; refrigerator It is 70-250 watts; the electric heater is 800-2500 watts; the electric oven is 800-2000 watts; the sterilizer is 600-800 watts; the electric iron is 500-2000 watts; the air conditioner is 600-5000 watts. When calculating the household electrical load, you can add up to the maximum power of the most frequently used appliances at the same time, preferring to take large numbers. If it is a new home, you must first figure out the capacity of the power supply facilities of the household, and then calculate the maximum power consumption of the electrical appliances used by the household. The power of the incoming and outgoing lines and the protection facilities should also be fully and fully considered during the renovation. Regardless of new and old homes, be sure to configure household appliances according to the capacity of the energy meter. If the capacity of the energy meter is less than the maximum capacity of the household appliance used at the same time, the energy meter must be replaced, and at the same time, whether the sectional area of ​​the household wire meets the capacity requirements.
